I sent a message to a list, which has 22 subscribers. One of the addresses gave me
the following error message:

user@xxx.edu....Can not check MX records for recipient host

This resulted in the message not being delivered to any of the recipients, although it showed
on the web archives.

Does anyone have any idea how I can avoid this from happening again??...If one address fails,
I would like for the rest of the messages to be delivered...Any suggestions??...I'm using
Listserv Classic.

Thanks
